On PSEG Long Island Rate 194, solar exports are banked in separate Time-of-Day buckets (Peak exports only offset Peak usage).

FAQ❓ Long Island (Nassau & Suffolk) (PSEG Long Island) Solar & Battery FAQsAnswers on local TOU windows, export credits, and battery payback
How does PSEG Long Island's Rate 194 Time-of-Day net metering work?
Under PSEG Long Island Rate 194, electricity is divided into Peak (weekdays 3 PM – 7 PM), Off-Peak, and Super Off-Peak (10 PM – 6 AM). Solar kWh exported during each time window are banked in that specific bucket to offset future imports in the same bucket.
Do Nassau and Suffolk County homeowners still get the $5,000 NY State Solar Tax Credit in 2026?
Yes! The New York State Solar Energy System Equipment Credit (25% of system cost up to $5,000) is a state statutory income tax credit (N.Y. Tax Law § 606(g-1)) completely independent of the repealed federal §25D credit, and it carries forward for up to 5 tax years.
